Company mission
Quizlet's mission is to give every student the tools and confidence to succeed, no matter their motivation or what they’re striving to achieve.
Role
Who you are
- Proven History of Architectural Ownership: and driving reliability initiatives within complex, distributed production environments as an SRE, DevOps, or Infrastructure Engineering role. We also welcome experienced Software Engineers (backend/systems) with a dedicated focus on reliability, performance, and operational excellence
- Core Systems Development: Proficiency in Go and/or Python, with a proven history of developing and deploying production-grade automation and control plane components for infrastructure teams. You must be experienced and comfortable providing hands-on operational support for critical, high-volume legacy codebases (like a PHP/HHVM/Hack monolith) while driving modernization efforts
- Kubernetes Control Plane Engineering: Deep operational and architectural knowledge of Kubernetes (GKE) and the complexities of service mesh (Istio) networking in a high-volume environment
- High-Volume Tooling: Expert experience with CI/CD systems (GitHub Actions, CircleCI, ArgoCD) and infrastructure-as-code tools (e.g., Terraform)
- Observability & Debugging: Mastery of high-volume monitoring and observability stacks like Datadog, and a proven ability to perform deep-dive root cause analysis under production load using systems like Jeli
- Systems Foundation: Solid understanding of Linux systems, networking, and the challenges of large-scale distributed cloud architectures on GCP (AWS or equivalent)
- At Quizlet, we’re excited about passionate people joining our team—even if you don’t check every box on the requirements list. We value unique perspectives and believe everyone has something meaningful to contribute
What the job involves
- We're looking for an experienced Site Reliability Engineer to be a systems developer who engineers the software, tools, and automation required to scale our platform for the next generation of AI features
- System Resilience & Self-Healing: Develop, test, and implement high-volume connection management and auto-scaling logic (in Go) for our Kubernetes clusters. Introduce and maintain self-healing and auto-remediation capabilities into core service layers to maintain 99.95% availability under peak load
- Dev Tooling & MTTR Improvement: Architect and implement tooling and automation that measurably improves our Mean Time To Resolution (MTTR)
- Optimize our CI/CD toolchain (GitHub Actions, CircleCI, ArgoCD) by writing and hardening deployment controllers and safety checks
- Deep Observability & Diagnostics: Design and deploy instrumentation within Datadog for high-volume monitoring
- Utilize deep-dive investigations and platforms like Jeli to drive architectural improvements that measurably reduce operational toil
- Architectural Consulting & Standards: Act as a senior subject matter expert, partnering directly with Product Engineering teams to review designs, define SLOs, and ensure new services are inherently resilient and operable before production deployment
- Data Layer Performance Tuning: Conduct advanced performance analysis and capacity planning for our transactional and analytical databases (Spanner, PlanetScale, BigQuery), optimizing query execution and eliminating hot-spotting
Our take
Quizlet has built a large-scale business around simple-to-share and simple-to-use products. Its free flashcard maker helps students prepare for exams. Those insights fuel Quizlet Plus, the startup’s subscription product that charges an annual fee for access to more features, including tutoring services.
After a long period of runaway growth, during which the company achieved a $1 billion valuation, Quizlet has been somewhat buffered by the general market downturn affecting the tech sector in 2022, which hit EdTech particularly heavily. It has responded by a shakeup of its leadership team, appointing AirBnB and Starship Technologies veteran Lex Bayer.
With an entrepreneurial management team and a strong user base of over 60 million students and teachers, Quizlet seems likely to weather the current economic situation and resume its growth in the near future.
